Google group word count for members?

I have a google group, and I'd like to figure out how many words each member has posted. Is there a utility to do this?

If not, how can I get started writing a Python script to do this? Should I just grab XML from the group's feed and look through that? (I don't know anything about Python's handling of XML.)

On 开发者_运维知识库the Google groups site, I see XML feeds for recent posts, but not for all posts.

It looks like people have wanted a Groups API since about 3 years ago. It looks like you may have to resort to page-scraping.
